Graetz Number given System properties Calculator

Graetz Number given System properties is a dimensionless number that characterizes heat transfer in duct flow. It is used to analyze the thermal development of fluid flows inside pipes or channels. The Graetz number is particularly important in the study of heat exchangers and microfluidic systems and is represented as Gr = (D*L_c*V_c*ρ*c)/(k*L) or Graetz Number = (Diameter*Characteristic Length*Characteristic Speed*Mass Density*Specific Heat Capacity)/(Thermal Conductivity*Length). Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere, Characteristic Length is a length scale used in fluid dynamics, heat transfer, and other fields of engineering and physics to define a dimension that characterizes the size of an object or system, Characteristic Speed is a physical quantity characterizing the average speed of motion of particles inside a single body or a particle system at rest, Mass Density is a physical quantity that represents the mass of a substance per unit volume, Specific Heat Capacity is the heat required to raise the temperature of the unit mass of a given substance by a given amount, Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance & Length is the measurement or extent of something from end to end.
